Structural Plastome Evolution in Holoparasitic Hydnoraceae with Special Focus on Inverted and Direct Repeats.
Article in Genome biology and evolution, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Plastome condensation during adaptation to a heterotrophic lifestyle is generally well understood and lineage-independent models have been derived. However, understanding the evolutionary trajectories of comparatively old heterotrophic lineages that are on the cusp of a minimal plastome, is essential to complement and expand current knowledge. We study Hydnoraceae, one of the oldest and least investigated parasitic angiosperm lineages. Plastome comparative genomics, using seven out of eight known species of the genus Hydnora and three species of Prosopanche, reveal a high degree of structural similarity and shared gene content; contrasted by striking dissimilarities with respect to repeat content [inverted and direct repeats (DRs)]. We identified varying inverted repeat contents and positions, likely resulting from multiple, independent evolutionary events, and a DR gain in Prosopanche. Considering different evolutionary trajectories and based on a fully resolved and supported species-level phylogenetic hypothesis, we describe three possible, distinct models to explain the Hydnoraceae plastome states. For comparative purposes, we also report the first plastid genomes for the closely related autotrophic genera Lactoris (Lactoridaceae) and Thottea (Aristolochiaceae).
